4. Strategy September, 2005 Define assumptions for interfering device
TX spectral mask
TX power
Hopping probabilties (if any)
Duty cycle
Define assumptions for interfered Rx device
Packet size
RX input filter (bandwidth and shape)
BER as function of interference plus noise power
Calculate the interference power for different frequency and distance scenarios
Assume the receiver of the interfered system to receive 10 dB above its specified sensitivity
Calculate the SINR for the different frequency and distance scenarios
Calculate the resulting BER
Calculate the resulting PER
Visualize the PER for the different frequency and distance scenarios
